Independent Upgrades: Like Floor 4, Floor 5 has its own soil upgrade path. Cash spent on Floor 5 upgrades only affects Floor 5 plots. This means you should not pour cash into lower-floor soil upgrades if you plan to farm primarily on Floor 5.
New Plot Layout: Floor 5 introduces a fresh plot arrangement optimized for the Carnival theme. The exact number of plots and their ring positions (Base, Middle, Outer) are being documented by early players.
Carnival Visual Theme: Bright colors, festival decorations, and Carnival-themed design elements distinguish Floor 5 from earlier floors. The visual change is cosmetic but helps identify which floor you're on at a glance.
Potential New Mechanics: There may be floor-specific mechanics tied to the Carnival event — such as special Carnival Pass interactions, boosted drop rates during certain conditions, or unique floor bonuses. These are unconfirmed and will be added once verified.
